Brake Adjustment w/Posi

Adjust just until the shoe drags, then go out on the street and put in reverse, get to about 10 MPH and put on the brakes. That’s what the self adjusters are for...

I have not used the self adjusters for 40 years. Don't trust them, so do my adjustments by ear. At least I did until I got a sure grip!
